I’ve been referenced here a couple of times so will briefly weigh in … firstly, the topic(s) are very broad - so broad, I don’t know where to begin or end - I could, if I had the desire, write a tome (literally) on these topics … I won’t do that, because I have a strong preference for the use of my time … which, oddly enough, is really the crux of why society often ends up in the structures that it does.
What I mean by that is that even though we might like things to be one way or another ideally, we, due to our Individual “time preferences”, will end up doing things that don’t actually involve some of our many individual ideals.
For example, a DAO structure is an interesting idea and agreeable to some of my own ideals, however achieving a DAO, complete with our particular specifications (not the off-the-shelf Ethereum code) places a hard limit on how quickly we could get the ball rolling as it’s outside of my personal knowledge area and I think, currently (because it’s novel), is outside the personal knowledge area of most people - someday that may not be the case, but until then the value of those who know these things is high and so their time-preference is going to the highest bidder … which is not going to be me. Given I do know a thing or three about founding organizations (just not DAO’s), then it makes the most sense for me, for the forseeable future, to use that knowledge toward making the world a better place (according to my time-preferences).
Because of time-preferences I also favor small focused groups that share similar time-preferences - sometimes these groups shrink to the size of one individual (again because of individual time-preferences) and hence there is no democracy … but there is efficiency, and so long as the overall group is happy to lend their support, then it is a sort-of democracy.
At the end of the day, IMO, getting all people to agree to voting on particular issues, only tends to make people anxious and frustrated - anxious because they will have to vote on something in which they are not an expert and frustrated because they don’t ‘prefer’ to put the time and energy into studying the prerequisites for the vote. Thus I’m strongly in favor of delegation, over democracy - particularly where the check on power is funding. i.e. if you don’t like it, don’t fund it.
Well those are my three bits. I don’t want to have a long discussion on this, so I may not respond to later comments - I’m a busy guy and this topic is only marginally of interest to me. Hopefully I’ve helped, at least a bit, and not inflamed or confused.
